Technical Field
[0001] This invention relates to the field of fabric testing technology, and in particular to a fabric light transmittance testing device. Background Technology
[0002] Throughout the development of the textile industry, fabric testing has always been a crucial step in ensuring product quality and performance. Traditional fabric testing equipment played a vital role in quality control for a long time. However, with technological advancements and the emergence of new fabric materials, its limitations have become increasingly apparent. Currently, the following problems exist in fabric testing:
[0003] 1. Limited detection dimensions: Traditional equipment uses a fixed light source (such as a single polarized light source), which cannot capture the sensitivity of the light transmission direction of anisotropic materials;
[0004] 2. Insufficient spectral coverage: Conventional sensors are mostly limited to the visible light band (380-780nm), making it difficult to identify ultraviolet / infrared transmission characteristics (such as the limitations of detecting polyester films).
[0005] 3. Poor environmental adaptability: It lacks a temperature and humidity / stress coupling detection module, making it impossible to assess the dynamic changes in light transmittance of environmentally responsive materials;
[0006] 4. Defect marking damage: Mechanical contact marking (such as in clamping components) can easily lead to damage to the nano-coating;
[0007] To address this issue, we propose a fabric light transmittance testing device. Summary of the Invention

A servo motor is installed at the upper end of one of the carrier boxes. The output shaft of the servo motor is connected to the upper end of one of the studs. A moving block is threaded onto the stud. An opening is provided on one side of the carrier box. A connecting block is fixed to one end of the moving block. One end of the two connecting blocks passes through the opening and is fixed together with a sealing plate. The upper end of the sealing plate passes through the side wall of the testing box and extends to the upper end of the testing box.
[0014] Preferably, guide rods are fixed between opposite sidewalls inside the carrier box, a moving block on the same side passes through a guide rod on the same side, gears are fixedly mounted on both studs, and the two gears are connected by a chain.
[0015] Preferably, the supporting mechanism includes a protective box fixed to one side of the bottom inside the detection box. The protective box is provided with a rotating mechanism, and a placement plate is installed at the upper end of the rotating mechanism. The placement plate is provided with a placement groove.
[0016] Preferably, the rotating mechanism includes an electric guide rail fixed to the upper end of an annular fixed frame, eight sliders are mounted on the electric guide rail, eight light source detection units are respectively fixed on one side of the eight sliders, fixed frames are fixed on both sides of the annular fixed frame, and the upper end of the fixed frame is fixed to the upper end of the detection box.

The light source detection unit adopts full-spectrum LED, liquid crystal phase delay film and metamaterial lens, which can provide multi-angle and multi-spectral light source, capture the light transmission direction sensitivity of anisotropic materials, and make up for the shortcomings of traditional equipment with single detection dimension.
[0027] 2. The use of full-spectrum LEDs means that the detection range is no longer limited to the visible light band, and it can identify the transmission characteristics of fabrics in the ultraviolet and infrared bands, which improves the comprehensiveness of the detection and overcomes the problem of insufficient spectral coverage.
[0028] 3. The nitrogen delivery mechanism can simulate different environmental conditions. Combined with the light source detection unit, it can evaluate the dynamic changes in light transmittance of environmentally responsive materials under different temperature, humidity, stress and other conditions, which solves the problem of poor environmental adaptability of traditional equipment and enhances environmental adaptability.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0039] Reference Figure 1-6A fabric light transmittance testing device includes a base plate 32, an AGV body 11 on one side of the upper end of the base plate 32, an intelligent robotic arm 12 on one side of the upper end of the AGV body 11, an adsorption mechanism connected to one end of the intelligent robotic arm 12, a testing box 31 on one side of the upper end of the base plate 32, a sealing mechanism on one side of the testing box 31, a bearing mechanism on the bottom inside the testing box 31, a ring-shaped fixing frame 3 on the upper end of the testing box 31, a rotating mechanism on the ring-shaped fixing frame 3, eight light source detection units 1 on the rotating mechanism, and a nitrogen delivery mechanism on both sides of the testing box 31. This device can capture the light transmittance sensitivity of anisotropic materials, making up for the shortcomings of traditional equipment with a single detection dimension, and can also identify the transmission characteristics of fabric in ultraviolet and infrared bands, thus improving the comprehensiveness of the detection.
[0040] The adsorption mechanism includes a clamping plate 14 installed at one end of the intelligent robotic arm 12. A support frame is connected to one side of the clamping plate 14. Multiple microporous ceramic plates 23 are installed at equal intervals on one side of the support frame. Multiple adsorption holes 24 are provided at equal intervals on the microporous ceramic plates 23. A vacuum pump 10 is installed on one side of the upper end of the AGV body 11. The suction end of the vacuum pump 10 is connected to a suction pipe 13. One end of the suction pipe 13 is connected to one side of the support frame. When the vacuum pump 10 is working, the suction pipe 13 causes the adsorption holes 24 on the microporous ceramic plates 23 to generate adsorption force, thereby achieving the adsorption of the fabric. When adsorbing different types of fabric, the magnitude of the adsorption force can be controlled by adjusting the power of the vacuum pump 10 to ensure that the fabric can be firmly adsorbed without damaging the fabric.
[0041] Both the bottom of the base plate 32 and the bottom of the detection box 31 are covered with magnetic strips 25. Rollers 9 are installed on both sides of the lower end of the AGV body 11. The magnetic induction device of the AGV body 11 corresponds to the magnetic strips 25. The magnetic strips 25 are made of high magnetic material. Their magnetic field strength is stable and evenly distributed, which can ensure that the AGV body 11 travels accurately along the preset path during movement (the error can be controlled within ±5mm). This allows the AGV body 11 to accurately transport the fabric into the detection box 31. The AGV body 11 is equipped with advanced obstacle avoidance sensors and an automatic navigation system. During transportation, it can detect the surrounding environment in real time and automatically avoid obstacles to ensure the safety and efficiency of the transportation process.
[0042] The sealing mechanism includes carrier boxes 6 fixed on both sides inside the detection box 31. Studs 16 are rotatably connected between opposite sidewalls within the carrier boxes 6. A servo motor 18 is mounted on the upper end of one of the carrier boxes 6. The output shaft of the servo motor 18 is connected to the upper end of one of the studs 16. A moving block 15 is threaded onto the stud 16. An opening 8 is provided on one side of the carrier box 6. A connecting block is fixed to one end of the moving block 15. One end of each of the two connecting blocks passes through the opening 8 and together fixes a sealing plate 17. The upper end of the sealing plate 17 passes through the sidewall of the detection box 31 and extends to the upper end of the detection box 31. Guide rods 7 are fixed between opposite sidewalls within the carrier boxes 6. A moving block 15 on the same side passes through a guide rod 7 on the same side. Gears 19 are fixedly mounted on both studs 16, and the two gears 19 are connected by a chain 20.
[0043] When the servo motor 18 starts, it drives the stud 16 to rotate. Since the stud 16 is threaded with a moving block 15, and the two studs 16 rotate synchronously through the gear 19 and the chain 20, the moving block 15 will move along the guide rod 7, thereby driving the closing plate 17 to rise or fall, realizing the opening and closing of the detection box 31.
[0044] The supporting mechanism includes a protective box 5 fixed to one side of the bottom inside the test box 31. The protective box 5 is equipped with a rotating mechanism. A placement plate 4 is installed at the upper end of the rotating mechanism. The placement plate 4 is equipped with a placement groove. The placement plate 4 is made of a smooth material, which can reduce the friction between the fabric and the placement plate 4 and avoid damage to the fabric during placement and testing.
[0045] The rotating mechanism includes an electric guide rail 22 fixed to the upper end of the annular fixed frame 3. Eight sliders 21 are mounted on the electric guide rail 22. Eight light source detection units 1 are fixed to one side of the eight sliders 21 respectively. Fixed frames 2 are fixed on both sides of the annular fixed frame 3. The upper end of the fixed frame 2 is fixed to the upper end of the detection box 31. The light source detection unit 1 includes a full-spectrum LED, a liquid crystal phase delay film, and a metamaterial lens. The full-spectrum LED can emit light close to the natural spectrum, providing an accurate light source for fabric transmittance detection. The liquid crystal phase delay film can precisely adjust the phase of the light, and the metamaterial lens can improve the focusing and transmission efficiency of the light, thereby improving the detection accuracy.
[0046] The nitrogen delivery mechanism includes two nozzles 26 fixed on both sides of the detection chamber 31. Two nozzles 27 are installed on one side of the nozzles 26. The nozzles 27 penetrate the side wall of the detection chamber 31 and extend into the detection chamber 31. A delivery pipe 29 is connected between the two nozzles 26 on the same side. A connecting pipe 28 is connected between the two delivery pipes 29. A nitrogen storage mechanism 33 is provided on one side of the upper end of the base plate 32. One end of the nitrogen storage mechanism 33 is connected to a nitrogen guide pipe 30. One end of the nitrogen guide pipe 30 is connected to one end of the connecting pipe 28. When a specific environment needs to be simulated, the nitrogen in the nitrogen storage mechanism 33 enters the nozzles 26 through the nitrogen guide pipe 30, the connecting pipe 28, and the delivery pipe 29, and is then sprayed into the detection chamber 31 by the nozzles 27. The nitrogen delivery mechanism adopts a precise flow control device, which can accurately control the amount and speed of nitrogen injection according to different detection requirements to ensure the stability and accuracy of the detection environment.
[0047] The workflow of this invention is as follows:
[0048] 1. Fabric adsorption: The adsorption mechanism at the end of the intelligent robotic arm 12 adsorbs the fabric. The vacuum pump 10 in the adsorption mechanism works, and the adsorption holes 24 on the microporous ceramic plate 23 generate adsorption force through the suction pipe 13, thereby firmly adsorbing the fabric. When adsorbing different types of fabric, the magnitude of the adsorption force can be controlled by adjusting the power of the vacuum pump 10 to ensure that the fabric is firmly adsorbed without damaging the fabric.
[0049] 2. Test box opening: The sealing mechanism is started, and the servo motor 18 drives the stud 16 to rotate. Since the stud 16 is threaded with a moving block 15, and the two studs 16 rotate synchronously through the gear 19 and the chain 20, the moving block 15 will move along the guide rod 7, thereby driving the sealing plate 17 to rise and opening the test box 31.
[0050] 3. Fabric transportation: Guided by the magnetic strip 25, the AGV body 11 moves using the rollers 9 to send the intelligent robotic arm 12, which is adsorbing the fabric, into the detection box 31 and place the fabric on the placement plate 4 of the carrying mechanism.
[0051] 4. Inspection preparation: The AGV body 11 exits the inspection box 31, the sealing mechanism is restarted, and the sealing plate 17 descends to seal the inspection box 31;
[0052] 5. Fabric inspection: The electric guide rail 22 on the ring-shaped fixed frame 3 drives the slider 21 to move, so that the eight light source detection units 1 scan and inspect the fabric.
[0053] 6. Environmental simulation: When a specific environment needs to be simulated, the nitrogen in the nitrogen storage device 33 enters the nozzle 26 through the nitrogen guide pipe 30, connecting pipe 28, and delivery pipe 29, and is then sprayed into the detection box 31 by the nozzle 27.
[0054] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
